Advance archaeological archaeology chronometric dating in in museum science
Radiocarbon dating technique is primarily based on the radioactive decay of Carbon-14 isotope.
Developed by a team of researchers under the leadership of Dr.
Another limitation is the difficulty in estimating the age of things which are older than 50000 years as the amount of C-14 in such samples become absolutely undetectable due to complete decay. F Herzog 60) conducted with the help of mass spectrometer have increased the range of the technique up to 100000 years (Nave).
Conclusion Despite all the limitations radio carbon dating will remain as a significant tool for archaeologist around the globe to compare and understand the evolution of human culture and civilization. Thus undoubtedly radiocarbon dating remains one of the significant tools for the archaeologist to explain the evolution and cultural emergence in a more accurate manner.
Understanding the age and period of existence of the excavated fossils and other organic objects will help the archaeologist to unravel human history and evolution in a scrupulous manner (Taylor 24).
Thus by comparing the relative quantity of carbon -12 and carbon -14 in an organic matter excavated scientists can predict the age of the object (R. Where N is the current amount, N_o is the original amount, lambda is the proportionality constant for the growth rate (which is negative for decay), and t is the amount of time that has passed. Source: (Brain, 2014) The half-life of carbon-14 is 5730 years.Since World War II, there has been tremendous success in the development of new methods for dating artifacts; the so-called `radiocarbon revolution' was only the first such discovery.The increasing accuracy of the various new techniques has brought about major changes in archaeological research strategies.Researchers from the field of Physics have discovered that radioactive molecules are unstable and they undergo decay to attain a stable structure at a specific rate which is directly determined by the atomic number and mass of the decaying atom (Polach, H. The isotope of carbon thus produced is radioactive and it will undergo decay at a constant rate (Berger and H. The carbon isotope is also absorbed during photosynthesis by plants and reaches animal body when they consume plant parts.It also reaches the organisms through respiration along with normal carbon-12.
